Solar-driven brine management system for hydrogen, chlorine production
Researchers have developed a novel energy system comprising PVT panels, reverse osmosis, reverse electrodialysis, and proton exchange membranes. The proposed setup can purportedly produce 18.78 kg/day of hydrogen and 120.6 m³/day of freshwater.
Balcony PV systems for cruise ships
Scientists have simulated the installment of PV modules on the balconies of cruise ship cabins. They tested the systems with three DC configurations and simulated them while cruising in the Caribbean and along the Norwegian and Danish coasts.
Roofit.Solar releases new BIPV panels with narrow roof coverage
Estonia’s Roofit.Solar has developed new building-integrated photovoltaic (BIPV) panels with an effective width of 470 mm, offering power outputs of 120 W or 180 W.
The case for combining pumped-hydro storage with floating PV
Researchers in Italy have analyzed the techno-economic viability of enhancing three pumped hydro plants in Italy with floating PV on the lower basin. They say that, with their wide results, consequences could be extrapolated to similar regions.
Mibet launches waterproof solar carport
The Chinese company said that its new product has a drainage edge that ensures complete waterproofing. It can purportedly withstand wind speeds of 45 m/s and a snow load of 1 KN/m².
New method to estimate soiling losses before PV project implementation
Scientists in Peru have proposed a self-contained, deployable system that quantifies energy losses from dust accumulation on PV modules. It uses both artificial neural networks and electrical models for soiling loss prediction.
Novel BIPV concept integrates louvers to enhance power production
Scientists have proposed a building-integrated PV system that integrates airflow to cool the panels and control room temperature. The system, which also acts as a shading device, can reportedly mitigate drops in power generation efficiency without additional energy consumption.
The best tilt angle to improve PV module performance in world’s worst soiling accumulation zone
Scientists have measured the performance of PV modules under strong soiling conditions in Saudi Arabia and have identified the most suitable tilt angles for improving power generation. They have also found that a key role is played by rain intensity, dust, sandstorms, and cloud cover.
Wind tunnel tests show spacing between panels is key to reduce soiling
Scientists have placed four PV panels in a 21-meter wind tunnel and run different tests regarding tilt angles, mounting height, spacing, and incoming flow direction. They found that when the spacing between panels exceeds twice the panel height, the mutual influence on dust deposition becomes negligible.
Open-source dataset for rooftop PV generation in urban environments
A group of scientists has developed an open-source dataset comprising three years’ worth of data from Hong Kong’s largest behind-the-meter rooftop solar power project. Power generation was collected at 5-minute intervals, and meteorological data at 1-minute.
